Nobody in their right mind would "sell" such a thing because it's illegal. You're going to end up making that, but the problem is the code it will set...
You have two options for programming:
1. disable EGR so the valve never opens
2. or, disable the error codes so it appears to function but does get efficiency errors when no flow occurs due to block-off plate.

My computer has already had EGR programmed out. I actually bought a EGR block off plate from summit but apparently its for the older SBC even though it says my year engine will work.

Right now I have no error codes, but the port is temp blocked and im trying to find a permanent solution before I look into making my own block-off.

I cut the tube and folded the ends like you would your tooth paste. Hammering it flat each time. I done this 6-10 folds.

Thats what I did too. Except I only folded it over once and I believe it has a leak. Im thinking im going to make a trip to Menards to try and see what I can find. If all else fails, i will see if I can get a big ass short bolt and screw it in.

The EGR motor has a pintle valve which opens and closes allowing in exhaust gasses when its open. When its closed there is no leak.
There might be some debris that could get in there, but so what? Its not going to go any furthur than the pintle valve. Unless you plan on adding EGR back later debris will do nothing. Any debris that did get in there woudl easily be removed with some brake cleaner and a shot of compressed air.

crane golds x3......as far as the block off, i used some brass pipe fittings from the local hardware store, and made a plate out of some stainless steel i had lying around from some old rocker paneling....i'll try to get some pics up

That is my motor above, and you do see my made EGR block off. But now I am trying to diagnose why bank 2 is taking away fuel while bank 1 is adding fuel... vacuum leak one would assume.

Do I need to plug the port on the intake manifold for the EGR tube as well as the block off plate? At first I didn't think so
